WILLARD -- Hundreds of people forced to evacuate after a railcar damaged in a train derailment in northern Ohio leaked flammable liquid have returned home.

CSX Corp. spokesman Gary Sease says he believes all affected residents in Willard had returned home by Sunday. He says more than 600 people came through an outreach center set up Saturday to help with compensation claims.

Crews have removed the soil impacted by the derailment, but expect to be at the site a few more days for final checks.

The railcar damaged in the derailment leaked about half of its 26,000 gallons of styrene monomer, which is used to make plastic and rubber products. Willard is about 65 miles southwest of Cleveland.

Sease says the investigation to determine what caused the derailment is continuing.
